I hope its not the PCM but we'll see. I tried to trace the wires last night to see if they are bad. Weird thing is, on the sensor the wires are a blue color and yellow. But according to the schematic in my Chilton manual they should be red and green
and go to the D10 and D11 plugs on the PCM. On my PCM the wires in D10 and D11 are black or gray. I'm really confused now. The diagram for the '91 has purple and yellow wires for the VSS and they go to B9 and B10 which are the right colors on MY PCM. I'm wondering if my car doesn't have the wiring from the 91 model or if the chilton manual is wrong? Like I said, I'm really confused now.
